"Process and corresponding device for the local dyeing of yarn bobbins"

The present invention relates to an in. Technique called "space-dying" for the local Dyeing of spools of thread, i.e. in particular spools of thread used in carpet manufacture and the like.

It is well known that carpets and the like are becoming these days according to a standard procedure with different color samples or Color shades which give them an uneven appearance Grant aspect, but in such a way that they still have, on the whole, sufficient uniformity and calm. There were already several yarn dyeing processes with a view to manufacturing Recommended for carpets of the aforementioned type. However, all known methods are either too complicated and therefore very time-consuming and expensive, or inexpedient in that they do not lead to the desired effect.

When dyeing the aforementioned types of yarn locally, the yarn is usually preprinted according to a specific pattern, which not only requires a very expensive system, but is also very time-consuming, or are fed back into the yarn bobbins by means of

409 8-U / 0879

Inserted needles are injected with shifting colors, which partially run into each other in the spool, and a certain color pattern produce. The color pattern obtained in this way is so irregular, that it turns out to be impossible for carpets made with such bobbins of thread to have a calm and beautiful appearance granted.

The present invention is now set the task of a new, simple, economical and useful process for the local dyeing of bobbins to create a very fast, economical and useful dyeing of the relevant Types of yarn with a view to producing with an irregular Colored pattern provided, but on the whole a calm and even appearance exhibiting carpets made possible.

The method according to the invention exists for this purpose essentially in a local paint liquid supply from the inside outwards into a lower part of the thread spool to be dyed. The invention not only relates to the aforementioned method, but also on all devices for the implementation of the same. The device according to the invention consists essentially from means or coil carriers, which allow an easy and quick arrangement and removal of the coils and with a cable for the supply of color liquid are connected under pressure, with passages in these carriers for the connection of the respective Supply line are provided with an outer part of the carrier arranged in the coil, so that the color liquid supply to the yarn in a lower part of the bobbin takes place from the inside to the outside.

Figure 1 is a schematic drawing of a thread bobbin 1 usually consisting of twine turns 2 with the actual support bobbin (yarn carrier) 3, which, as is well known, always has a conical shape and almost over its entire surface area their total height with openings M- in the form of holes, slots and the same is provided.

The coil shown in Figure 1 is arranged with its longitudinal axis horizontally, with one of the two ends Means for the supply of a pressure fluid supplied, for example, by a pump, are provided according to the arrow 6. The supply of the aforementioned liquid consisting of a suitable coloring agent takes place in such a way that it passes through the openings 4 of the carrier 3 opposite the supply opening

can penetrate to the interior of the yarn mass 2 with regard to dyeing the yarn such that the part extending below the arbitrary line A-A (Figure 2) is colored and the part extending above this line A-A remains uncolored. Both sides of the line A-A forms automatically a transition area between the dyed and the undyed part, consequently the yarn regularly alternating after unwinding Has parts of a different color in relation to its original color, the distance of which can be chosen arbitrarily each time by changing the respective circumstances. This leads to the one, lower part of the yarn is completely dyed from the core to the outer surface as a result of the liquid supply under pressure, while the other, upper part remains uncolored. The excess liquid can easily be secured and drained off.

Figures 3 and f relate to one method of implementation of the system according to the invention, which only differs from that explained by FIGS. 1 and 2 distinguishes that the longitudinal axis of the coil 1 with the horizontal forms an angle, which results in a significantly different local color of the yarn and thus a completely different one Color samples of the carpet made from this yarn lead. Tests have shown that according to the pictures 3 and 4 explained system of dyed yarn a much nicer effect than that according to the one explained in Figures 1 and 2 System dyed yarn causes.

Of course, the yarn bobbins can be dyed according to the method according to the invention, i.e. by supplying dye liquid under pressure from the inside out into one end of the spool,

4098U / 0879

2345S45

take place when they are inclined with respect to the horizontal or vertical Spools of yarn, the angle between the bobbin axis and the horizontal or vertical in each case according to the desired Effect is to be chosen.

A second stage of the process according to the invention consists in that the yarn dyed in the manner described above unwound from the spool even when wet and wound onto another spool with changed or unchanged Screw thread (Figure 5), whereupon the yarn wrapped in this way immediately a second time according to the method described above is colored, the bobbin axis at an arbitrary angle to be selected according to the desired effect with the horizontal or Vertical forms. This angle may or may not correspond to that of the first stage of treatment. This second dyeing with the same or another color liquid creates an additional effect and so a different color pattern in the carpet.

It is readily apparent that the above-described The dyeing process can be repeated several times with a view to a thorough change in the color pattern of the one treated in this way Yarn-made carpets. The hue, the angle of inclination of the bobbin and the helix of the wrapped yarn are different or the same in the successive dyeing stages. This offers the great advantage that the wrapping and re-dyeing the thread spools can take place continuously, as you don't have to wait until the thread is dry. This, of course, turns out to be as extremely favorable for the production capacity of the system, as well as for the efficiency of the dyeing process. It is readily apparent ' that the inventive system described above to a particular

ders simple, convenient and economical method for the local dyeing of yarn results, the treated in this way Yarn alternates at regular intervals with its original color, color transitions and identically or differently colored parts, what an arbitrary influencing of the color pattern with the according to the invention treated yarn enables carpets to be produced. Such a carpet is shown schematically as an example in Figure 6 reproduced. Parts 7 have the original color and parts 8 (transition parts) have a different color, while the Parts 8 that are parts colored one or more times. As said above, lets you increase the number of colors arbitrarily by repeatedly dyeing the spools of thread.

This leads to a very irregular pattern that gives the carpets made with the yarn in question a uniform one and beautiful appearance granted.

On the picture 7 is a thread spool 1, which usually consists of the thread turns 2 and the actual spool (thread carrier) 3 consists, shown schematically. It concerns here the simplest embodiment of the device according to the invention « It consists of the frustoconical part 5, the cone angle that of the aforementioned coil (carrier) 3 corresponds. This part 5 has an axially or almost axially extending blind bore 10, which is connected to the outer wall of part 5 by means of a transverse bore 11.

According to the invention, the part 5 is preferably mounted at an angle and connected to a line 12 which opens into the aforementioned bore 10 and at the same time acts as a support for the part 5. The operation of the device in question is very simple

and can be described as follows.

After arranging a bobbin 1 on the aforementioned frustoconical part 5 (Figure 7), the line 12, the bore 10 and the bore 11 supplied paint liquid under pressure, so that they through the openings 4 of the actual Bobbin, i.e. the actual bobbin carrier 2, penetrates into the lower part of the yarn mass. This process is carried out on the Figure 8 illustrates where line A-A is the intersection of the interface between the lower colored and the upper uncolored Is part of the yarn mass.

The colored liquid text supply under pressure offers the advantage that on the one hand the liquid text excess is slightly downwards the thread spool can flow off and, on the other hand, that the two colors i.e. the original color of the thread and the supplied color, mix with each other in a transition area on either side of the dividing line A-A, resulting in a gradual transition from the lower one colored zone after the upper uncolored zone. Another advantage of the aforementioned liquid supply under pressure forms the fact that the part of the yarn mass extending below the line A-A is completely from the core to the outer wall is colored.

Figures 9-17 show a complete system for dyeing yarn bobbins according to the method according to the invention reproduced in a detailed manner. It is mainly about the dyeing of inclined yarn bobbins. The concerned The system consists essentially of a common central line 13, which also functions as a carrier preferably alternating left and right, the aforementioned

Lines 12 are arranged. These lines connected to the pipe 13 12 form a certain angle with the horizontal.

The tube 13 is located above the container 14, at least in place of the yarn bobbins 1 to be locally dyed for collecting the excess paint liquid, and is connected to a collecting container 16 by means of a junction 15, which is optionally equipped with a heating element 17 and is connected by a line 18 to a pump 19, at the inlet port of which a line opening into the aforementioned container 14 20 is connected. In the present case, one half of a part 5 (see above) is attached to each line 12. It is about in particular by a frustoconical design over the greater part of its height and with a circumferential collar at the bottom 22 provided block 21. This block 21 provided with an internal thread 23 is screwed onto the relevant line 22, which is provided with an external thread. The conical part of the block 21 is designed such that it is exactly in the Coil 3 fits, while the diameter of the aforementioned collar 22 is slightly larger than the largest inner diameter of the coil 3 for the purpose the formation of a stop on the rear side of the same. The aforementioned bore 10 is also here in connection with a bore 11, of which the outwardly directed end is preferably extended with a part 24 of larger diameter.

The block 21 is also with one or more, provided with the aforementioned bore holes that are parallel or nearly parallel. In the present case it is the two holes 25 and 26, which extend over the entire height of the block. With the block 21 is suitably a

second axially displaceable block 27 connected, which is designed conical over a large part of its height, wherein its cone angle corresponds to that of the coil 3, while its upper end does not touch the inner wall of the coil 3 when it is in its Operational situation is. The side edges of the aforementioned block 27 are preferably cut off (see numbers 28 and 29 on the figures) to create a space between the block and the adjacent inner wall of the coil on both sides. It This concerns the two spaces 30 and 31, which extend over the entire length of the block 27.

In the present embodiment, the two above are Blocks 21 and 27 connected to one another, for example, as follows. On the block 21 is a screw 32 stainless plate 3 3 attached, which is provided with one or more pins, here with two pins 34 and 35, the head 36 or 37 can play the role of a guide element for the block 27 provided with a T-groove for this purpose. That The lower end of this T-groove 38 is closed, for example, with a stop plate 39 which is fastened with one or more screws HO is attached to the block 27. The figures shown in Figures 9-17 described system has almost the same mode of operation as the one by Figure 7 explained. It can be described as follows.

Each bobbin 1 is arranged on a block 21 in such a way that the lower edge of the bobbin carrier 3 against the collar 22 the same is applied. Then the block 27 is pressed into the coil until it is with the adjacent inner wall of the relevant. Coil carrier 3 comes into contact. This simple system enables

light a strong fastening of the coil 3 on the blocks 21 and 27 exclusively by the fact that the block 27 inwards, is moved parallel to the longitudinal axis of the block 21.

As soon as the bobbins 1 have been arranged on the carriers 21-27 in the manner described above, the actual dyeing can begin

kick off. For this purpose, the aforementioned container m is filled with a suitable amount of paint liquid and the pump 19 is then switched on, which pumps the liquid over from the container IU into the collecting container 17, where it is usually heated by the device 17. The liquid reaches the pipe 13 through the conductor 15 and is distributed via the lines 12, each of which is connected to a bore 10-11 of a part 21. Finally it reaches the lower part of the various bobbins through the holes H of the bobbin carrier 3, as a result of which this lower bobbin part is colored under pressure according to the method already described with reference to Figures 7-8, the color spreading over the entire thickness of the bobbin.

In order to create a gradual transition between the colored ones extending below the line A-A (Figure 8) Part and the uncolored part extending above this line, the excess liquid is drained away. To this For this purpose, the parts 21 and 27 are provided with the holes 25-26 and the passages 30-31. This has the consequence that the excess fluid on the one hand seeps out of the yarn mass and on the other hand through the holes 25-2 6 and the possibly existing spaces 30-31 flows back into the container 14 and recirculated will.

As can be seen from the previous description, leads

the system according to the invention to an extremely simple and expedient one Device for the local dyeing of yarn, whereby the yarn dyed in this way is differently colored after unwinding. rich at regular intervals, i.e. uncolored areas where the yarn is in its original color, transition areas and colored areas. There is also the option of Wrap yarn spools after a first dyeing process, if necessary, and dye them a second time with a view to better color distribution. For example, carpets made with yarn dyed according to this process have the parts shown in Figure 6 and appearance shown schematically.

As stated above, the present invention is of course in no way limited to that described in the preceding lines and system explained by the accompanying drawings, but refers generally to all systems which lead to equivalent results with equivalent means within the scope of the invention.
